Morrisons, who will also use the duo in television advertising campaigns, said it wanted to highlight what it claims is its main point of difference from its supermarket rivals: its 5,000 trained butchers, bakers and fishmongers.

The deal will include 15-second “bumpers”, short films that lead in and out of advertising breaks, showing its staff at work.

“This puts us in the homes of millions of potential new Morrisons customers every Saturday night,” said chief executive Dalton Philips.

“We want to shout about and showcase the talent shoppers won’t see in any other supermarket.”

A Morrisons spokesperson said staff could feature in the two shows as a number had applied to appear in Britain’s Got Talent.
